History

History
The element Zirconium was discovered by Martin Heinrich Klaproth in year 1789 in Germany. Zirconium derived its name from from Persian Zargun, 'gold-colored'; German Zirkoon, 'jargoon'
The element Polonium was discovered by Pierre Curie in year 1898 in France. Polonium derived its name derived its name from from Named after the home country of Marie Curie(Poland), who is also the discoverer of Radium
